Vulnerability discussion

AUTOERASE will force TSS to erase all residual information on DASD.The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during migration process or contingency plan activation.

Fix text

The IAO will ensure AUTOERASE control option is set to (YES) for Classified systems and is at the sites discretion for Unclassified systems to erase all residual information on DASD. Evaluate the impact associated with implementation of the control option. Develop a plan of action to set the AUTOERASE control option to (YES) for classified systems and implement.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
